1 entalities. for supporting the ironing parts (Figure l) consist ci atable having a top ll and end nges t, to which are attached legs t bymeans oi bolts t. The legsare braced by means of end braces t and Varear brace t. Sup- 35j ported beneath one end' oil the table is a motorl, held in spaced relationship near the table by means of scers tthrough which screws t pass for supporting the motor on the table.

The motor shait is provided with a motor m coupling it by which themotor is operatively f connected to a worin shait ior transmitting powerto the moving parts ci the ironing machine. in one corner and on top ofthe table is a name-plate it, which has therein a switch it for cuttingthe current on and od oi the heating unit.4 The motor is provided with alead cord il, which on its -end a plug for connecting the cord to asuitable sociret in the vExtending from the switch are wires itiorfconducting current to These es extend through a derdble conduit it,which has Aone end suitably attached to bach oi the shoe.

casing ill integral with and extending upwardly from the gear housingfloor 22. Immediately beneath the bearing 20 and around the worin shaftare leather` washers 23, which have beneath them a retaining washer 24.The bearing 23 is held within the casing 2| by means of a set Around theshaft I3 and resting upon the bearing 20 is a thrust washer 23, whichhas above it a worm shaft collar 21 attached to the shaft by means of apin 23. The worm of the shaft is indicated by lthe numeral 29. 'Iheupper end of the worm shaft is supported by means `of an arm 3|) whichextends from the rear of the housing toward the open side 1 thereof. Theworm 23 engages a worm gear 3| on theshaft 32 and has integral therewitha pinion 33Y which meshes with a gear 34. The shaft 32 is supported bymeans of a boss in one side of the gear housing.

The gear 34 is loosely mounted upon a drive or roll shaft 35 and is heldagainst longitudinal mhcvelsient on the shaft by means of 4a cotter phousing and adjacent the top thereof (Figure 3) is a cone-shapedprojection 31, which has therein a cylindrical sleeve 33. This sleeveextends through a back 33a of the housing and;y has attached thereto aroll tube 33. Within this roll tube 33 is a collar 4l1secured thereto bya pin 4`l. This collar is located around the roll shaft and between theroll shaft and the roll tube, and serves as a retainer for a bearing 42located -between the roll shaft and the roll tube.

Adjacent the bearing are felt washers 43. The roll shaft has .thereon aclutch member 44 ladapted to move longitudinally thereof and to rotatetherewith through the instrumentality of The clutch 44 is adapted toengage a clutch 46 on the hub part of the gear 34 so that when theseclutch elements are inlengagement the rotation of the gear 34 will causethe shaft 3l to rotate. "The clutch 44 ,is provided with a groove 41 toreceive the yoke end 53 of a lever 43 pivoted at the point 43 on thefloor of the housing. s This arm is acted upon by means of a spring Itending to hold the clutch members in engagement.

'I'he roll shaft 35 and the roll tubehave mounted thereon a roll 52(Figure l), which is hollow and cylindrical and has at each end acup-shaped end member 53, each of which has an outwardly extendingflange or cylindrical part `54 to which a tubular member 53 is attached.Extending inwardly from each end member and in a direction opposite thatof the flange 54 thereof, is an inner tubular member Il'adapted torotate around the roll tube and supported on the roll tube by means ofroller bearings 51.

The roll shaft 35 extends longitudinally mrough the roll and is attachedat its free end Extending rearwardly from the gear A sion 33 between theshaft and the end of the roll tube remote from the'gear housing. Theroll locking knob 53 is attached to the end member`53 remote from thegear housing by means of a drive pin 60a. This end member has itstubular member 56 provided withroller bearings 51 between it and theAroll tube. The roll shaft is provided with a spiral groove 6I for thepurpose of transmitting lubricant from the gear housing to the endoftheroll tube remote from the housing. Around the roll 52 are layers ofmaterial for building up the circumferential part of the roll. There is,rst, a pad- 62 about which there is an under cover 63 and an outer cover,84. Located in the gear housing and adjacent the floor thereof (Figures2 and 3) is an inwardly projecting boss 55 having a bore which supportsa control shaft tube 31, having therein a control shaft 33. Around theshaft and between the shaft and the) control tube is an oil seal packingring 33 of any suitable and conventional type. Secured to the outer endof the control shaft 35, as by the pin 69a, is the hub of a cam lever 33(Figures 2 and 3.). On the free end of the arm 63 is mounted a bolt 10.which has thereon a head for engagement with a cam surface 1I on thelever 48. The lever has thereon a projection 12 so `arranged that thehead "of the bolt cannot pass from the lever in its movement toward thetop wall of the gear housing.

One end of the control shaft 63 is supported by the structure justdescribed, while its otherend is `supported by means of a bracket 13(Figure 1) suitably attached to the top of the table. 0n the end of thecontrol shaft beyond the bracket 13 and held thereon by means of' setscrews and a collar 15 is the hub 14 of a downwardly extending arm 11,-which is longi justed with relation to the pressure lever so it mayextend either to the righthand side or t0 the lefthand side of thepressure lever. To the arm 11 (Figure 4). is attached one end of aspring 33 which tends to hold the foot'rest in its forward position.Extending upwardly from .the hub 14 is an arm 34 which has.attachedthereto one `end lcf each of ytwo springs, one a pressure spring 35 anda second pressure spring 33 (Figure 4).

The hub 14 is provided with a socket 14a arranged to receivey a plunger34a, which 'is reciprocably mounted in a bore in the bracket 13. urgedtoward the socket 14a by a spring 34h and operated by means of a knob34e (Figure l). I'his plunger 34a projects beyond the lug supporting itand in the path of tnearm 34 for holding this arm 34 in position withrelation to the roll. By withdrawing the plunger 34a from the socket 14athe arm 34 may be moved backward, carrying with it the shoe so as toprovide a wider space between'the shoe and the roll. The second-spring38 is jor the purpose of holding the shoe in .proper position when theshoe is withdrawn from engagement with the ironing roll.
